Commonwealth Fusion Systems (CFS) announced collaborations with NVIDIA and Siemens to develop a digital twin of its SPARC fusion machine that will apply artificial intelligence (AI) and data and project management tools to accelerate commercial fusion. The digital twin will leverage troves of data from the Siemens Xcelerator portfolio of industrial software, including its Designcenter NX for advanced product engineering and Teamcenter product lifecycle management (PLM) tools, which CFS uses to create, catalog, and process machine designs and assemblies. These designs and assemblies can then be used in CFS' modeling and simulation workflows, including the layering of AI-enabled tools.

CFS will use NVIDIA Omniverse libraries and OpenUSD to integrate data with classical and AI-powered physics models to create the digital twin of SPARC. This virtual replica of SPARC will provide CFS with a user-friendly way to run simulations, test hypotheses, and quickly compare the experimental results from the machine to the simulations. This ability to rapidly analyze data and iterate will speed CFS' efforts to make fusion energy a commercial reality.

CFS is also using Siemens' digital tools to improve the efficiency of its manufacturing processes and operations at the company's magnet factory in Devens, Massachusetts.
